A lot of hardware resources as well as electricity is thereby wasted. Most of the time, computers today only use a fraction of their potential power and run with low average system loads. Virtualization can signiﬁcantly reduce hardware and electricity costs. You can delete snapshots while a VM is running to reclaim disk space. Any number of snapshots can be created, allowing you to travel back and forward in virtual machine time. after installing misbehaving software or infecting the guest with a virus), one can easily switch back to a previous snapshot and avoid the need of frequent backups and restores. This way, one can freely experiment with a computing environment. On top of that, with the use of another VirtualBox feature called “snapshots”, one can save a particular state of a virtual machine and revert back to that state, if necessary. Once installed, a virtual machine and its virtual hard disks can be considered a “container” that can be arbitrarily frozen, woken up, copied, backed up, and transported between hosts.

Installing and running a mail server becomes as easy as importing such an appliance into VirtualBox.

With VirtualBox, such a complex setup (then often called an “appliance”) can be packed into a virtual machine. For example, installing a complete mail server solution on a real machine can be a tedious task. Software vendors can use virtual machines to ship entire software conﬁgurations. Since you can conﬁgure what kinds of “virtual” hardware should be presented to each such operating system, you can install an old operating system such as DOS or OS/2 even if your real computer’s hardware is no longer supported by that operating system. This way, you can run software written for one operating system on another (for example, Windows software on Linux or a Mac) without having to reboot to use it. VirtualBox allows you to run more than one operating system at a time. VirtualBox provides are useful for several scenarios: Running multiple operating systems simultaneously. VirtualBox is a powerful virtualization product for enterprise as well as home use. Targeted at server, desktop and embedded use, it is now the only professional quality virtualization solution that is also Open Source Software.
